The five networks were chosen as typical of different approaches to network implementation and management: Defense Advanced Research Projects Agency (ARPA) Network, MERIT Network, Triangle Universities Computation Center (TUCC), Oregon State Regional Network, and Tymnet (a commercial network). A common format which included questions about network mission, technology and organization; financial and legal concerns; and summary of problems and tentative recommendations was used to survey each organization. The resulting report is not intended to be prescriptive, although some empirical observations are presented for each topic covered.

The Bureau's overall goat is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (I) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, t 3) a technical basis for equity in trade. and (4) technical services to promote public safety, The Bureau consists of the Institute for Bask Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, and the Office for Information Programs. THE INSTITUTE FOR BASIC STANDARDS provides the centrAt basis within the United States of a complete and consistent system of physical measurement; coordinates that system with' measurement systems of other nations; and furnishes essential services leading to accurate and uniform physical measurements throughout the Nation's scientific 'community, industry, and commerce. The Institute consists of a Center for Radiation Research, an Office of Meas. urement Services and the following divisions: A2plied Mathematics Electricity -- Mechanics Heat Optical Physics Nuclear Sciences' -- Applied Radiation' Quantum Electronics' Electrornagneticsa Time and Frequency' Laboratory Astrophysics' -- Cryogenics'. THE INSTITUTE FOR MATERIALS RESEARCH conducts materials research leading to improved methods of measurement, standards, and data on the properties of well-characterized materials needed by industry. commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; and develops, produces, and distributes standard reference materials. The Instituteconsists of the Office of Standard Reference Materials and the following, divisions: Analytical Chemistry Polymers Metallurgy Inorganic Materials Reactor Radiation Physical Chemistry. THE INSTITUTE FOR APPLIED TECHNOLOGY provides technical: services to promote the use of available technology and to facilitate technological innovation in industry and Government; cooperates with public and private organizations leading to the development of technological standards (including mandatory safety standards), codes and methods of test; and provides technical advice and services to Government agencies upon request. The Institute consists of a Center for Building Technology and the foltossi.,g divisions and offices: Engineering and Product Standards Weights and Measures Invention and Innova- tion Product Evaluation Technology Electronic Technology Technical Analysis Measurement Engineering Structures, Materials, and life Safety' Building Environment' Technical Evaluation and Application' Fire "I tAnology. THE INSTITUTE FOR COMPUTER SCIENCES AND TECHNOLOGY conducts research and provides technical services designed to aid Government agencies in improving cost effec- tiveness in the conduct of their programs through the selection, acquisition, and effective utilization of automatic data processing equipment; and serves as the principal focus within the executive branch for tare development of Federal standards for automatic data processing equipment, techniques, and computer languages. The Instituteconsists01 thefollowing divisions: Computer Services Systems and Software -- Computer Systems Fngineering Infoona- tion Technology. TILE OFFICE FOR INFORMATION PROGRAMS promotes optimum dissemination and accessibility of scientific information generated within NBS and other agencies of the Federal Government; promotes the development of the National Standard Reference Data System and a system of information analysis centers dealing with the broader aspects of the National Measurement System; provides appropriate services to ensure that the N8S staff has optimum accessibility to the scienffs information of the world. The Office consists of the following organizational units: Office of Standard Reference Data Office of Information Activities Office of Technical Publications Library Office of International Relations.
